Thaum nws los tsim cov roj teeb pob, Li-ion cells yog ib qho kev xaiv zoo tshaj plaws yam tsis muaj kev poob siab. Tab sis yog tias koj tau txais lawv los ntawm lub roj teeb laptop qub ces koj yuav xav ua lub peev xwm ntsuas ua ntej tsim lub roj teeb pob.

Yog li hnub no kuv yuav qhia koj yuav ua Li-ion lub peev xwm ntsuas siv Arduino li cas.

Yog li cia peb Pib

Kauj ruam 1: Saib Video

Yog tias koj tsis xav nyeem txhua yam khoom koj tuaj yeem saib kuv cov vis dis aus!

Kauj Ruam 2: Txhua Yam Peb Xav Tau

1) PCB (Kuv xaj online tab sis koj tuaj yeem siv Zero PCB)-https://www.gearbest.com/diy-parts-components/pp_6…

2) Lub zog tiv thaiv -https://www.gearbest.com/diy-parts-components/pp_2…

3) 10k Resistor-

4) OLED-https://www.gearbest.com/lcd-led-display-module/pp…

5) Arduino-

6) Buzzer-

7) Ntsia Hlau Terminal-

8) Poj Niam Headers-

9) IRFZ44N N Channel Mosfet-https://www.banggood.com/2Pcs-IRFZ44N-Transistor-N…

Kauj Ruam 3: Muaj Peev Xwm Li Cas

Ua ntej tsim lub peev xwm ntsuas peb yuav tsum paub tias lub peev xwm yog dab tsi. Chav rau lub peev xwm yog mAh lossis Ah. Yog tias koj saib ntawm ib qho Li-ion cell lawv yuav hais txog nws lub peev xwm ntawm nws raws li ib qho qhia hais txog 2600 mAh ntawm nws. Yeej qhov no txhais tau li cas, yog tias peb txuas lub nra hla nws uas thim 2.6A ces lub roj teeb no yuav nyob ntev li ib teev. Zoo sib xws, yog tias kuv muaj roj teeb 1000 mAh thiab rub 2A ces nws yuav nyob ntev li 30 feeb, Thiab qhov no yog Ah lossis mAh txhais li cas.

Kauj Ruam 4: Xyaum Ua Tsis Tau

Tab sis suav nrog txoj hauv kev no yog qhov ua tsis tau vim peb txhua tus paub V = IR. Thaum pib, peb lub roj teeb hluav taws xob yuav yog 4.2V yog tias peb ua kom tsis muaj qhov tsis sib xws yuav muaj qee qhov tam sim no ntws los ntawm kev thauj khoom. Tab sis dhau sijhawm lub roj teeb hluav taws xob yuav txo qis thiab peb li tam sim no. Qhov no yuav ua rau peb cov lus teb nyuaj dua li qhov xav tau vim peb yuav xav ntsuas tam sim no thiab lub sijhawm rau txhua qhov piv txwv.

Tam sim no los ua txhua qhov kev suav nws tsis tuaj yeem siv tau yog li ntawm no peb yuav siv Arduino uas yuav ntsuas lub sijhawm tam sim no thiab qhov hluav taws xob, ua cov ntaub ntawv thiab thaum kawg muab lub peev xwm rau peb.

Kauj Ruam 5: Schematic, Code & Gerber Files

Nco tseg!

Kuv muaj SPI OLED dag ib puag ncig yog li hloov nws mus rau I2C thiab siv nws. Yog tias koj xav kawm yuav hloov SPI rau OLED li cas ntawm kuv qhov kev qhia yav dhau los -https://www.instructables.com/id/OLED-Tutorial-Con…

Nov yog qhov txuas rau kuv Txoj Haujlwm yog tias koj xav hloov pauv PCB thiab Schematic

Kauj ruam 6: Ua haujlwm

Thiab ntawm no yog qhov Circuit Court ua haujlwm li cas, thawj Arduino ntsuas qhov ntsuas hluav taws xob tsim los ntawm 10 ohm resistor yog tias nws siab dua 4.3v ces nws yuav tua MOSFET tso tawm hluav taws xob siab, yog tias nws tsawg dua 2.9v nws yuav tso tawm qhov hluav taws xob qis thiab tua MOSFET thiab yog tias nws nyob nruab nrab ntawm 4.3v thiab 2.9v nws yuav qhib rau MOSFET thiab lub roj teeb yuav pib tso tawm los ntawm tus tiv thaiv thiab ntsuas tam sim no siv txoj cai ohms. Thiab nws kuj tseem siv lub luag haujlwm millis los ntsuas lub sijhawm thiab khoom ntawm tam sim no thiab lub sijhawm muab rau peb lub peev xwm.

Kauj ruam 7: Soldering

Tom qab ntawd kuv pib txheej txheem txheej txheem ntawm PCBs uas kuv xaj online. Kuv pom zoo siv Poj niam lub taub hau zoo li koj xav tshem OLED lossis Arduino rau lwm qhov haujlwm tom qab.

Tom qab cov laug thaum kuv txuas lub zog qee zaum nws tsis ua haujlwm raws li qhov xav tau. Tej zaum vim tias kuv tsis nco qab ntxiv Pull Up resistors ntawm I2C BUS interface yog li rov qab mus rau txoj cai thiab siv Arduinos Built-in Pull Up resistors. Tom qab uas nws ua haujlwm txig

Kauj Ruam 8: Ua Tsaug

Nws ua haujlwm!
